Whether used as a base layer during colder days or as our main layer on mild days during high-exertion activities, the Swix Horizon Pant is our go-to for an insulated performance pant. The Horizon Pant features an insulated front panel only and is loaded with PrimaLoft Silver for a high warmth-to-weight ratio. The 360-degree ventilation allows our body to breathe during high-output activities, and the thin and stretchy rear panel helps to regulate our temperature. The full-length side zippers allows us to customize our airflow, and an elastic waistband makes for the perfect fit.
